Elastomers yog feem ntau yog cov thermosets(yuav tsum tau vulcanization) tab sis kuj yuav yog cov thermoplastic (saib cov thermoplastic elastomer). … Raws li qhov tshwm sim ntawm qhov yooj yim heev, elastomers tuaj yeem thim rov qab los ntawm 5–700%, nyob ntawm seb cov khoom siv tshwj xeeb.
Yog elastomers thermosetting?
Elastomers tau txhais los ntawm lawv cov deformability loj heev nrog qhov tseem ceeb ua kom tiav rov qab..
Dab tsi yog qhov txawv ntawm qhov ntsuas kub thiab elastomer?
Thermosetting plastics yog ib qho nyuaj, glassy polymer cov ntaub ntawv uas nyob mus ib txhis cross-linked peb- dimensionally ntawm cov tshuaj valence bonds.… Elastomers yog cov yas ruaj khov uas yog, txawm li cas los xij, elastically mouldable thiab muaj qhov hloov pauv iav uas qis dua qhov kev thov kub.
Puas yog roj hmab puas yog thermoplastic?
Cov yam ntxwv ntawm cov khoom siv nplaum Cov roj hmab thermoplastic yog cov chav kawm tshiab ntawm polymer Nws muaj cov solubility thiab thermoplasticity ntawm polystyrene, thaum nyob rau hauv qhov kub thiab txias nws muaj lub toughness. thiab resilience ntawm vulcanized ntuj roj hmab los yog polybutadiene.
TPE puas zoo dua roj hmab?
Txawm hais tias cov ntaub ntawv TPE tau txhim kho zoo heev hauv 20 xyoo dhau los, lawv tseem feem ntau qis dua ntawm cov khoom ntawm lub cev. Tag nrho lwm qhov sib npaug, cov ntaub ntawv roj hmab ib txwm muaj lub zog tensile zoo dua, elongation, thiab tshwj xeeb tshaj yog compression set.
